ABSTRACT:
A rotary variable resistor wherein a pair of levers are arranged in a case, a knife-shaped cam has its one end pivotally mounted on a projection of each lever, and the cam comes into engagement with a tooth portion of a toothed wheel in accordance with the operation of the lever so as to turn a slider holder. The moving stroke of the lever can be made small, and the slider holder can be turned every small angle.
